SME cannot be more than secured by mortgages on immovable property and ADC exposures (C 09.01.a, EBA rule v0410_m)

A warning in the own funds and capital requirements return (COREP own funds), on template C 09.01.a, geographical breakdown of exposures by residence of the obligor (SA exposures).

Check your file against this ruleWhat to do if it fails

The rule in plain words

SME cannot be more than secured by mortgages on immovable property and ADC exposures.

EBA checks it for four columns: original exposure pre conversion factors, exposure value, risk weighted exposure amount pre supporting factors and pre FX-mismatch, and risk weighted exposure amount after supporting factors and after FX-mismatch. That makes four checks. A failure names the one that failed.

How the Line4 Check report words itShow

The first of its checks, word for word as the report shows it when it fails. The others read the same, with their own column, row or sheet.

RISK WEIGHTED EXPOSURE AMOUNT AFTER SUPPORTING FACTORS AND AFTER FX-MISMATCH: Of which: SME <= Secured by mortgages on immovable property and ADC exposures

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Compare the values in your file. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  3. 03EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C 09.01 as reported.
  5. 05This is a warning. It does not stop the filing on its own, but your authority may ask you to explain it.

A worked example

The first of its checks, with simple numbers.

Illustrative values
SME1,200
What the rule then expects

Secured by mortgages on immovable property and ADC exposures must then be at least 1,200.

1,200Passes
1,100Fails

A file that reports 1,200 passes. One that reports 1,100 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

EBA's formula, as written out for the first of its checks. Cells are written as {template, row, column, sheet}.

{C_09.01.a,r0095,c0090,} <= {C_09.01.a,r0090,c0090,}

The next three:

{C_09.01.a,r0095,c0080,} <= {C_09.01.a,r0090,c0080,}{C_09.01.a,r0095,c0075,} <= {C_09.01.a,r0090,c0075,}{C_09.01.a,r0095,c0010,} <= {C_09.01.a,r0090,c0010,}

Checks like this one, run at the point of submission, are the first step to real-time supervision.
